Geranium Plant Named ‘Fisbarock’

ABSTRACT

A new and distinct cultivar of geranium plant named ‘Fisbarock’, as described and illustrated, and particularly characterized by the combined features of dark-red, double flowers, medium-green, only slightly zoned foliage, medium flowering response, and relatively vigorous, though dense and well-branched, growth habit.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of geranium plant, botanically known as Pelargonium peltatum, and hereinafter referred to by the cultivar name ‘Fisbarock’.

‘Fisbarock’ is a product of a planned breeding program which had the objective of creating new ivy geranium cultivars with dark-red, double flowers in combination with moderately vigorous growth and well-branched plant habit.

‘Fisbarock’ originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Galdar, Gran Canaria, Spain, in 1994. The female parent was the variety ‘Fisbliz’ (U.S. Plant Pat. No. 9,373), characterized by white, single-type flowers, medium-green foliage with slight zonation and vigorous growth. The male parent was a hybrid seedling, designated no 323-1 (unpatented), derived from a cross between the commercial variety ‘Guishiva’ (U.S. Plant Pat. No. 9,351) and the variety ‘Fisam’ (U.S. Plant Pat. No. 8,327). ‘Guishiva’ is characterized by deep-red, semi-double flowers, small leaves with distinct zonation and relatively compact growth habit. ‘Fisam’ is characterized by light-violet, double flowers, zoned foliage and comparatively vigorous growth.

‘Fisbarock’ was selected as one flowering plant within the progeny of the stated cross by the inventor, Angelika Utecht, in 1995 in a controlled environment in Galdar, Gran Canaria, Spain.

The first act of asexual reproduction of ‘Fisbarock’ was accomplished when vegetative cuttings were taken from the initial selection in autumn 1995 in a controlled environment in Galdar, Gran Canaria, Spain, by, or under the supervision of, Angelika Utecht. Horticultural examination of plants grown from these cuttings, initiated in the spring of 1996 in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisbarock’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fisbarock’, which in combination distinguish this geranium as a new and distinct cultivar:

1. Dark-red, double flowers;

2. Relatively large, semi-spherically-shaped inflorescences;

3. Medium-green, relatively large, slightly zoned foliage;

4. Moderately vigorous growth and medium-tall, well-branched plant habit; and

5. Medium spring flowering response.

‘Fisbarock’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity and day length without any change in the genotype. The following observations, measurements, and comparisons describe plants grown in Hillscheid, Germany, and in Langley, British Columbia, Canada, under greenhouse conditions which approximate those generally used in commercial practice.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fisbarock’ is the variety ‘Fisrock’ (U.S. Plant Pat. No. 10,365). In comparison to ‘Fisrock’, ‘Fisbarock’ has an almost similar flower color, somewhat larger flowers and inflorescences, wider, only slightly zoned leaves, and a different plant habit. ‘Fisbarock’ grows generally more vigorously and develops up to twice the number of branches as ‘Fisrock’, thus forming a dense, bushy and moderately-tall plant. ‘Fisrock’ has a more upward developing plant habit and ‘Fisbarock’ is rather flat-spreading or trailing.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic illustrations show typical flower and foliage characteristics of ‘Fisbarock’ with colors being as true as possible with illustrations of this type.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Langley, British Columbia, Canada, on Jun. 15, 1999, 12 weeks after planting of rooted cuttings into 15-cm pots. The plants had not been pinched. In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Colour Chart. The color values were determined indoors from plants developed in a greenhouse in May 1999 in Hillscheid, Germany.
